Someone just left a string of anti-Semitic comments on an old post of mine. It is one of those posts that still gets a reasonable amount of traffic because it ranks high on some apparently popular google searches. So, do I delete the comments?
Part of me wants to leave them up for posterity's sake. But I've become attuned to how hideous comment trolling can really affect people's sense of well-being on the internet, and I don't want to contribute (particularly since random folks who aren't regular readers might come across the post). Advice?
